MEANS FOR CONTROLLING ACTION OF OSCILLATING DISKS IN WATER-METERS-SPECIFICATION forming part of Letters Patent No. 535,640, dated March12, 1895.

Application filed April 18,1894. Serial No. 508,001. (No model.)

To all whom it may concern.-

Be it known that I, JOHN THOMSON, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Means for Controllingthe Action of OscillatingDisksin Water-Meters, of which the following isa specification.

This invention relates to disk water meters, and consists of means forcontrolling the action of the oscillating disks in water meters by theemployment of suitable apparatus actuated by flotation.

In the single figure of the drawing, B represents the ball and disk; 0,the disk-casing; E, the disk spindle, and D a main casing of such a diskaction as might be applied to water meters; the connecting gear trainand the ports of ingress and egress being omitted.

As shown, the disk-spindle passes entirely through the ball; its lowerend, as, being connected to the hollow sphere J, which is to be sealedagainst the introduction of water and so proportioned as to effect asufficient displacement to be actively buoyant. Hence, as the sphereconstantly tends to rise, denoted by the arrow m, it will exert aconstant power upon the disk to cause it to mutate in contact with thefrustums of the casing. Obviously, the sphere will also act to partiallyor wholly relieve the sockets of the weight of the ball and of the disk.Moreover, if particles of foreign material should be introduced betweenthe disk and the frustums, the disk and ball will Vibrate and pass overthe same, thus causing the sphere to swing inwardly toward the centerline r; but immediately the obstruction is passed, the sphere will againfloat outward and upward, re-setting the disk to its normal position.

It is to be observed the correct operation of this device involves thatthe sphere shall. be

disposed below the disk operating in a water chamber, as S, and that themedium line P, of the disk casing shall lie in a horizontal plane.

While I prefer the use of a hollow metallic sphere, it will be apparentthat the form may be varied and that its equivalent, such as a floatconstructed of wood or cork, would also effect the same result.

What I claim is 1. In a disk water meter, an oscillating disk providedwith a buoyant device attached to a projecting end of the disk spindle,said device operating in a water chamber extraneous to the disk-casing,the arrangement and construction being such that the disk is caused toadhere to the frustums by flotation, substantially as described.

2. The combination with a disk-casing, disk, ball and spindle, of abuoyant device as a hollow sphere connected to a projecting end of the.spindle and operating in a water chamber extraneous to the disk-casing,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN THOMSON.
